Penjelajahan adalah rasa ingin tahu yang mengarah pada petualangan. - Wilbur Wright

What is chiefly needed is skill rather than machinery. The flight of the buzzard and similar sailors is a convincing demonstration of the value of skill and the partial needlessness of motors.
It is possible to fly without motors, but not without knowledge and skill. This I conceive to be fortunate, for man, by reason of his greater intellect, can more reasonably hope to equal birds in knowledge than to equal nature in the perfection of her machinery...

Hawks are better soarers than buzzards but more often resort to flapping because they wish greater speed. A damp day is unfavorable for soaring unless there is a high wind. No bird soars in a calm. The object of the tail is to increase the spread of surface in the rear when the wings are moved forward in light winds and thus preserve the centre of pressure at about the same spot. It seems to be used as a rudder very little. In high winds it is folded up very narrow.

More than anything else, the sensation [of flying] is one of perfect peace mingled with an excitement that strains every nerve to the utmost - if you can conceive of such a combination.
